Abstract
In this paper, activity coefficients of tin atoms is studied in diffusing from tin atoms to substrate surface of iron in 260∼350. The activity coefficient of tin reduced gradually with the weight percentage of tin diffused into the iron layer increased at different temperatures. The ratio of initial activity coefficients and balance activity coefficients tends to decrease.The activity coefficient decreased rapidly to near zero with the temperature and the difference of activity coefficients gradually becomes more gentle with the temperatures increasing.
